NQN-REFILLABLE BOTTLE.

Application filed July 13, 1912.

To all whom, it may concern:

Be it known that I, J OHN MoGINNInss, a citizen of the United States, residing at Longbeach, in the count-y of Los Angeles and State of California, have invented a new and useful NonRefillable Bottle, of which the following is a specification.

The invention relates to improvements in non-refillable bottles.

The object of the present invention is to improve the construction of nonrefillable bottles, and to provide a simple, inexpensive and efficient device, capable of elfectively preventing a liquid from being surreptitiously introduced into a bottle or analogous receptacle after the same has received its original contents without destroying the valve mechanism and thereby indicating that the mechanism has been tampered with.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing :Figure 1 is a vertical sectional view of a non-refillable bottle, constructed in accordance with this invention. Fig. 2 is a plan view, the stopper being removed. Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 1. Fig. 4 is a similar view on the line 44 of Fig. 1. Fig. 5 is a detail perspective view of the valve disk.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

In the accompanying drawing in which is illustrated the preferred embodiment of the invention, 1 designates a bottle provided with a truncated or stub neck 2, but the improvements are applicable to jugs and various other receptacles having a neck. The walls of the stub neck 2 are thickened and are provided at the top with an interior annular recess 3, forming a horizontal annular shoulder or seat 4, surrounding the passage through the short stub neck and receiving a valve 5. The valve which is constructed of thin glass, is exceedingly light and is nor- Speoification of Letters Patent.

mally maintained against the shoulder or seat by a coiled spring 6, located within an extension neck 7 and fitting against the upper or outer face of the valve disk 5 adjacent to the periphery thereof and over the shoulder or seat 4, so that the spring pressure on the valve will not tend to fracture the same, whereby the valve disk may be constructed of exceedingly thin glass. In practice the pressure of the spring will be about five times the weight of the valve disk, so that when the contents of the bottle have been decanted and the valve seat is not subjected to internal pressure, the spring will firmly hold the valve disk in its closed position and will effectually prevent the valve from being opened by shaking the bottle. This will prevent refilling of the bottle by shaking the same while the bottle is submerged in liquid. Also the glass disk is sufficiently thin to cause it to be blown to pieces should an attempt be made to force a liquid into a bottle by the use of a pump.

The extension neck is provided with an enlarged cylindrical lower portion 8, fitted on and suitably secured to the short or stub neck 2 and forming an interior recess, which has a horizontal top wall 9 to fit against the upper edge of the neck 2 of the receptacle. The top wall 9 of the extension neck is provided with depending projections 10, forming stops and arranged in the path of the valve disk to limit the outward or opening movement thereof to permit the liquid contents to flow around the valve when the latter is open.

The extension neck is provided at an intermediate point with a horizontal partition 11, forming upper and lower chambers 12 and 13 and provided with a central opening 14 for the passage of the contents of the bottle in decanting the same. The coiled spring 6, which is located within the lower chamber 13, is interposed between the lower face of the partition 11 and the valve disk, and its coils are arranged in close proximity to the walls of the said lower chamber 13.

The upper chamber 12 of the extension neck is adapted to receive a stopper 15, as illustrated in dotted lines in Fig. 1 of the drawing, and the central opening 14 is covered by an approximately dome-shaped guard 16, formed integral with the partition and arranged at the upper face thereof in the lower portion of the upper chamber 12 and provided with lateral outlet openings 17 to permit the liquid to flow freely from the bottle. The lateral ope-nings 17 while forming outlets for the liquid and vents for the inlet of air will in practice be of a size to prevent an instrument from being introduced into the lower portion of the extension neck and interfering with the operation of the valve. The coiled spring by being of a relatively large size and located adjacent to the walls of the extension neck is arranged out of the way and if a wire or other instrument were forced into the neck, the valve disk would be broken before it could be held open.

What is claimed is 1. In a device of the class described, the combination with a receptacle including a neck and having a horizontal valve seat, a relatively light valve disk constructed of thin fragile material and arranged on the said seat and adapted to be brokenwhen subjected to abnormal external pressure, a transverse partition extending across the said neck in spaced relation with the valve seat and having a passage through it, and a coiled spring located below the partition and having its lower end coil bearing against the upper face of the valve disk directly over the valve seat at the supported portion of the said disk to prevent breakage of the valve through the pressure the spring thereon.

2. A device of the class described including a receptacle having a short nek interiorly recessed to form a flat horizontal annular valve seat, an extension neck secured to the short neck of the receptacle and having an interior diameter greater than that of the passage through the said short neck at the valve seat and provided with a horizontal partition having a passage for the discharge of the contents of the receptacle, a light valve disk of thin fragile material arranged on the valve seat and adapted to be broken when subjected to abnormal external pressure, and a relatively large coiled spring interposed between the partition and the valve disk and having its lower end coil bearing against the supported portion of the same directly over the said seat, whereby breakage of the valve through the pressure of the spring thereon is prevented;

In testimony, that I claim the foregoing as my own, I have hereto afiixed my signa ture in the presence of two witnesses.
